Question

In which region, the transistor as a switch is ON?

• A. Saturation
• B. None of these
• C. Active
• D. Cut-off

Answer 1

The correct option is A Saturation

If the transistor is operated in the saturation region then it acts as a closed switch (ON) and when it is operated in the cut-off region then it behaves as an open switch (OFF).

Hence, option $\left(A\right)$ is the correct answer.
